TNN Vitamin B12
Vitamin B12, tseem hu ua cobalamin, yog polycyclic compound uas muaj 3-valent cobalt. Plaub qhov txo qis pyrrole rings tau koom ua ke los tsim lub Gulin macrocycle (zoo ib yam li porphyrin), uas yog tib cov vitamin-muaj hlau. Vitamin B12 yog xim liab crystalline hmoov, tsw tsw thiab tsw. Me ntsis soluble hauv dej thiab ethanol. Nws yog qhov ruaj khov tshaj plaws hauv cov kua qaub me ntsis nrog tus nqi pH ntawm 4.5 ~ 5.0. Decomposes nyob rau hauv muaj zog acid (pH).

Daim ntawv thov
1. Txhawb kev hloov methyl
2. Txhawb txoj kev loj hlob thiab kev loj hlob ntawm cov qe ntshav liab, coj lub cev hematopoietic muaj nuj nqi mus rau lub xeev ib txwm, tiv thaiv pernicious anemia; Tuav Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv
3. Nyob rau hauv daim ntawv coenzyme, nws muaj peev xwm ua rau kom siv cov folic acid thiab txhawb cov metabolism ntawm carbohydrates, rog thiab proteins.
4. Nws tuaj yeem qhib cov amino acids, txhawb cov nucleic acid biosynthesis, thiab txhawb cov protein synthesis. Nws ua lub luag haujlwm tseem ceeb hauv kev loj hlob thiab kev loj hlob ntawm cov menyuam mos
5. Metabolize fatty acids kom cov rog, carbohydrates thiab cov protein siv tau los ntawm lub cev
6. Tshem tawm kev ntxhov siab, mloog zoo, txhim kho kev nco thiab kev nkag siab ntawm kev sib npaug
7. Nws yog ib qho tseem ceeb vitamin rau kev noj qab haus huv lub paj hlwb kev ua haujlwm thiab koom nrog hauv kev tsim cov lipoprotein hauv cov paj hlwb.
Ua ntej, txhim kho qhov kev siv ntawm folic acid, synthesize methionine (synthesized los ntawm homocysteine) thiab choline nrog rau folic acid, thiab synthesize cyanocobalamin los ntawm kev tsim cov purine thiab pyrimidine, xws li methylcobalamin thiab coenzyme B12, uas koom nrog hauv cov txheej txheem methylation. ntau cov ntsiab lus tseem ceeb. Thaum cov vitamin B12 tsis txaus, methyl pab pawg hloov pauv kev ua haujlwm los ntawm methyltetrahydrofolate txo qis, ua rau folic acid ua tsis tau zoo, ua rau folic acid tsis txaus.
Qhov thib ob yog txhawb cov metabolism thiab ua haujlwm ntawm paj hlwb myelin. Tsis muaj vitamin B12 tuaj yeem ua rau muaj kab mob hauv lub paj hlwb, txha caj qaum degeneration thiab cov tsos mob ntawm kev puas siab puas ntsws loj. Tsis muaj vitamin B12 tuaj yeem ua rau peripheral neuritis. Thaum ntxov tshwm sim ntawm vitamin B12 tsis txaus nyob rau hauv cov me nyuam yog txawv txav mus ob peb vas, npub qhia, qeeb cov tshuaj tiv thaiv thiab thaum kawg ua rau anemia.
Thib peb, lawv txhawb txoj kev loj hlob thiab loj hlob ntawm cov qe ntshav liab. Methylmalonyl coenzyme A yog hloov mus rau succinyl coenzyme A, uas koom nrog hauv lub voj voog tricarboxylic acid. Succinyl coenzyme A yog txuam nrog heme synthesis.
Plaub, vitamin B12 kuj koom nrog hauv kev sib txuas ntawm deoxynucleic acid (DNA), cov metabolism hauv cov rog, carbohydrates thiab cov protein, thiab tseem ua rau cov synthesis ntawm nucleic acid thiab protein ntau.
